3 times slower than c++?
Dear all, I wrapped a c++ code into python. It works but it is 3 times slower than the orignial c++ one. Is that normal? Is there something I can do to speed it up?

Python slower than C++? I don't believe it ! ...;-) regards Andy Little

Hey No offence intended, but AFAIK( which isnt well) Python is built to be lightweight and versatile rather than for speed performance. regards Andy Little

That's not what he's asking: his C++ code is apparently slower when called from python than when run standalone. This is off-topic for Boost though, even if it's actually true (I'd like to know how the measurement were carried out, or rather I wouldn't, because it's off topic!). This should be moved to a more appropriate discussion list. Your friendly neighbourhood moderator, John.

Please bring your Boost.Python questions to the C++-sig. Haven't I suggested that many times in the past? http://www.boost.org/more/mailing_lists.htm#cplussig Someone ont that list can answer you. -- Dave Abrahams Boost Consulting www.boost-consulting.com
